I have not, but I don't see how it could possibly be much of an upgrade. I shy away from anything Venturi. There were Venturi autococker bolts, and inserts. They had the usual marketing junk attached to them about accuracy, being soft on paint, etc.

Practically speaking, soft tips and Venturi style things don't do as much (if anything) as they advertise. Actually, restricting airflow like that (as opposed to the open face bolt that's stock) would slightly diminish air efficiency. You won't experience any less breaks from having a soft tip, and most people don't notice a real big improvement from things like pillow bolts.

My advice? Save your money. Besides, I think FEP is going to release their new bolt engine for the next gen Quest as a drop in replacement for the current engine. I think it's compatible. So, instead of getting a new bolt now, just wait. It'll most likely be a bigger improvement.
